Answer: the answer is cell wall
Explanation:The cell wall is an outer protective membrane in many cells including plants, fungi, algae, and bacteria. Animal cells do not have a cell wall. The main functions of the cell wall are to provide structure, support, and protection for the cell
Student 2 is right.
<h3>Constant variables</h3>
In research investigations, some variables should be kept constant across various experimental groups in order for the outcome of the investigation to be valid.
For example, in order to test how flatworms respond to different environments, one variable that should be kept constant is the flatworms. The flatworms to be used must be of the same species, sex, age, etc.
The investigator can then go ahead to divide the flatworms into two or more groups and then subject them to different environments. Other variables should also be kept constant in order to determine the effects that are only specific to the different environments only.

#SPJ1
A carbon footprint measurement helps check the ecological issue of global warming that the world is currently facing. The correct answer is A.
Answer:
The correct answer is - create polypeptide and eventually proteins for gene expression.
Explanation:
This model is representing the translation process in protein synthesis which takes place in the cytoplasm of the cell and results in forming proteins from the information carried by mRNA from DNA in a code. The translation is the process that translates the code, carried out by mRNA with help of ribosome and tRNA, into a chain of amino acids called polypeptide chain that forms eventually in protein.
1. mRNA strand and ribosome present of ER translate codes into a protein.
2. Amino acids are transferred by the tRNA molecules to the ribosomes.
3. mRNA and tRNA bases are paired and amino acids are left behind to create polypeptide.
